Today I saw this website -
deshitalk which looks to be useful for O2 customers but I am not sure. The website says -
- Free International Calls From Your Mobile inclusive cross network minutes
- You do not have to pay a penny, just use your FREE or inclusive minutes from O2 ONLY
- Call 0333 313 4339
- Enter the number you want to call in international format followed by the # key
- Your will receive an SMS with a Direct Dial (DD) number which is connected with your given destination number to dial
- The 07 number allocated will only works on your registered phone
I have not tried this service (as I am not O2 customer), in case anyone finds this useful, please post your feedback.
